Mold for manufacturing part e.g. fly-wheel central part, of vehicle e.g. motor vehicle such as car, by material injection, has face forming general angle with respect to perpendicular axis so as to facilitate flow of injected material

摘要

The mold (M) has faces (F1, F2) defining a part of a masking zone (ZA) in a wall, where one face (F1) receives injected material front of another face (F2), and forms a general angle (theta1) with respect an axis (X) perpendicular to an internal face (FI) of the mold. The former face forms another general angle (theta2) with respect to the perpendicular axis so as to facilitate flow of the injected material. The former general angles are between 50 and 80 degree. The latter general angle is between 5 and 20 degree. An independent claim is also included for a part of a vehicle.
